Malignant neoplasm of bone and articular cartilage of other and unspecified sites (C41)

Browse all the diagnosis codes used for malignant neoplasm of bone and articular cartilage of other and unspecified sites (c41). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Clinical Information

Cementoma - An odontogenic fibroma in which cells have developed into cementoblasts and which consists largely of cementum.

Chondrosarcoma - A slowly growing malignant neoplasm derived from cartilage cells, occurring most frequently in pelvic bones or near the ends of long bones, in middle-aged and old people. Most chondrosarcomas arise de novo, but some may develop in a preexisting benign cartilaginous lesion or in patients with ENCHONDROMATOSIS. (Stedman, 25th ed)

Chondrosarcoma, Clear Cell - A chondrosarcoma of adolescence to old age of the proximal EPIPHYSES of long bones. It has variably clear cytoplasm of the mostly neoplastic CHONDROCYTES with little intervening matrix.

Chondrosarcoma, Mesenchymal - A rare aggressive variant of chondrosarcoma, characterized by a biphasic histologic pattern of small compact cells intermixed with islands of cartilaginous matrix. Mesenchymal chondrosarcomas have a predilection for flat bones; long tubular bones are rarely affected. They tend to occur in the younger age group and are highly metastatic. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1456)

Chordoma - A malignant tumor arising from the embryonic remains of the notochord. It is also called chordocarcinoma, chordoepithelioma, and notochordoma. (Dorland, 27th ed)

Clavicle - A bone on the ventral side of the shoulder girdle, which in humans is commonly called the collar bone.

Coccyx - The last bone in the VERTEBRAL COLUMN in tailless primates considered to be a vestigial tail-bone consisting of three to five fused VERTEBRAE.

Costal Cartilage - Bars of HYALINE CARTILAGE extending from the anterior ends of the upper RIBS. They attach to the STERNUM directly or indirectly by connecting to upper costal cartilage that attaches to the STERNUM. Costal cartilages extend the ribs anteriorly and contribute to the enhanced elasticity of the THORACIC WALL.

Enchondromatosis - Benign growths of cartilage in the metaphyses of several bones.

Ischium - One of three bones that make up the coxal bone of the pelvic girdle. In tetrapods, it is the part of the pelvis that projects backward on the ventral side, and in primates, it bears the weight of the sitting animal.

Mandible - The largest and strongest bone of the FACE constituting the lower jaw. It supports the lower teeth.

Nucleus Pulposus - Fibrocartilage inner core of the intervertebral disc. Prolapsed or bulged nucleus pulposus leads to INTERVERTEBRAL DISC DISPLACEMENT while proliferation of cells in the nucleus pulposus is associated with INTERVERTEBRAL DISC DEGENERATION.

Osteosarcoma - A sarcoma originating in bone-forming cells, affecting the ends of long bones. It is the most common and most malignant of sarcomas of the bones, and occurs chiefly among 10- to 25-year-old youths. (From Stedman, 25th ed)

Osteosarcoma, Juxtacortical - A form of osteogenic sarcoma of relatively low malignancy, probably arising from the periosteum and initially involving cortical bone and adjacent connective tissue. It occurs in middle-aged as well as young adults and most commonly affects the lower part of the femoral shaft. (Stedman, 25th ed)

Pubic Bone - A bone that forms the lower and anterior part of each side of the hip bone.

Sternum - A long, narrow, and flat bone commonly known as BREASTBONE occurring in the midsection of the anterior thoracic segment or chest region, which stabilizes the rib cage and serves as the point of origin for several muscles that move the arms, head, and neck.

Instructional Notations

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
